Salinity is an important
abiotic stress which reduces the productivity and quality of agricultural areas
by also negatively affecting plant growth and development. This study was
conducted to determine changes on some morphological, physiological and
biochemical parameters caused by different salt concentrations as well as to
determine the effect of exogenous salicylic acid (SA) application on these
changes for basil plant (Ocimum
basilicum L.) which has an
economical value due to its nice odor and essential oil content. Plant heigth,
number of tree branches, fresh and dry herbal weights, pigment contents of
leaves and antioxidant enzyme activities decreased for plants on which only
NaCl (25 and 50 mM) application was made but foliar SA application was not;
while malondialdehyde (MDA) content and essential oil ratios increased on
leaves of the plants. While plant heigth, number of tree branches, fresh and
dry herbal weights, pigment contents of leaves did not generally change for
plants which were subjected to NaCl stress after foliar SA application; MDA
content, essential oil ratios and antioxidant enzyme activities increased. This
study has shown that exogenous SA application decreased in general negative effects
caused by salt stress.
